So yesterday I decided to shoot my broadheads again just to make sure they were still on from the last time I shot them. I am using NAP Thunderhead Razors. I started at 20yd and worked back to 30yd. First arrow dead on at 20yd. Second and third arrows were about 1-1/2" low and one right and one left about the same. I stepped back to 30yd and both of these arrows were dead on and one passed through. I use one of the foam targets from Walmart to tune my broadheads so it doesn't surprise me that it passed through. After the pass through I shot a couple more times and they were still dead on and penetrating farther than at 20yd. I went back to 25yd and they were dead on there also. I have spin tested all three of my arrows and if they are off at all I couldn't tell. They seemed to be perfect. I may go out and try it again today just to make sure it wasn't me shooting a little off after all I had been shooting about 30 minutes before I shot my broadheads. Could my arrows still be accelerating at 20yd causing them to be off? Should I even worry about this little bit of difference?
The arrow starts decelerating the minute it leaves the string. The impact difference could be due to a number of things but I aminclined to think they are due to shooter inconsistancy. As you said, you may have been a bit tired and fatigue was causing the problem and when you check again with fresher arms you may find no inconsistancy.
What size vanes are you using? When I use fixed blades I go to a four inch vane and will notice much more consitancy than with the two inch. With the two inch ill get a flyer every once in awhile but with the four inch it almost never happens.
After you shot 3 arrows at 20 yards with two hitting low, how many more arrows did you shoot at that distance? Were they still hitting low?
Unless your arrows are equipped with a 2 stage rocket, they can't be accelerating. So, like Bruce said, it was most likely shooter inconsistency.
I shot the two that hit low 2 more times a piece. They were inconsistent left to right but, still low.
I was pretty sure of that but, as with other things in archery, sometimes things arent as we would think they would be.
I was using them with fixed blades before and they worked ok but for me the four inch are the way to go. I know guys that swear by the quickspins and I think they work well but ive done extensive shooting with two, three and four inch vanes and the four inch vanes ALWAYS grouped better for me especially with fixed blades. I will lose about 8fps going from two to four inch wich translates into about two inches lower at thirty yards. I probably wouldnt be to worried about it if I were getting three inch groups at 25yds which even with your shots that are off it sounds like you are. I also have some three inch fusion vanes that work well with fixed blades and they are very quiet in flight if you wanted to try some I could send you a few.
I'm going to shoot some more later today and make sure it wasn't me before I do any major changing. I am not too concerned with the change but, at the same time it does bother me as I am trying to be dead on with every shot. I want to know with out a doubt I am hitting dead on when I draw back on a deer. Right now I am wanting to think it was me due to shooting a normal 30 minute session before I decided to shoot the broad heads and the fact I was dead on at 30yd with every shot. Most of my sets are less than 20yd from deer trails. There is always that wondering deer that might be out past 20yd though. Guess we will see what happens later today.
If your heads are now on different arrows it could be part of the problem , could have just gotten lucky before , that is why i always float my shafts in the bath tub and mark the high side which will always be to the top no matter what , with my set up my cock vane is up so it works out perfect for me ......and i dont get any flyers they all fly the same.
It was me. Arms must have been gassed. 30 minutes is usually a normal session and I can usually hold accuracy for an hour of constant shooting 3 arrow groups. I didn't even think about it but, for the past two weeks I have been working on our house hot and heavy so my arms are a little sore and given out. Its catching up with me now. I should only have about three more weeks of this hard work and then a week to rest up for the opener. Unfortunately I will not b able to practice as much this season due to 15 credit hours but, I feel like if I get in a couple 20-30 minute sessions a week, I will be good to go. Thanks for everyones advise on this. I feel sure it will come in handy broadhead tuning my wifes bow and mine when I have to again.
Perhaps you are too concerned about being 1.5" off at times? The deer is dead either way. There is being anal (good thing) and then there is being overly anal (bad thing). Keep in mind we are not shooting firearms here. It's a string pushing a long shaft. Take archery for what it is. 1.5" is not something to be that concerned with. In fact... good shooting.
Same heads on the same shafts. New QF's though. I will have to remember that when I build my nest arrows though. Sounds like a good thing to do. Thanks for that tip.
So is the high side the spine of the arrow? Have you experimented with the location of the high side in relation to the cock vane? I have never heard of this and I'm going to make uo some arrows tonight so ill try it and see how it goes.
I hear ya , i guess i'm overly anal then.......lol...... because i get and have my heads all flying perfect ....... if two or three of 12 arrows are shooting 1.5'' to 2'' off of the others its completly unexceptable.......:D
I bet you will like it , take one that is floating and mark the left side of it and fletch it up and shoot it from 30 or 40 yards tell me how it shoots compaired to the others that are identical ........just an example think of a log floating in the water , roll it around it will always come back to the same spot for a reason..........:D
Heads or the shooter? If it's the set-up... no question fix it. If it's shooter inconsistency (as I thought was previously decided on) no big deal.
I am a perfectionist when it comes to shooting. I want to be the best shot I know. lol I am some what the competitive type. Before I got into hunting and now especially bow huning, I was the same way about sport bike riding. Fastest, smoothest knee dragging beast is what I pushed myself to be. 4 wrecks and 2 totalled bikes later I was just that with the group I road with on a regular bassis. I didn't really do it to outrun the other guys. It was more for me to prove to myself that I could get better no matter how good I was doing. Once my son was born I had to hang up the leathers and sale the bikes. Guess thats one reason I chose to go the Industrial Engineering rout. continual improvement. This shows it's face in pretty much everything I do.
